lowing is a specification.

- broken off, the shoe being ried by a piston rod 6 This invention relates to .a device for stopping an automobile, lifting one wheel from the ground, and preventing skidding, said device being carried by the axle and not connected to the wheel, and operated from the drivers seat, the device being normally suspended in an inoperative position an when released dropping into operative position by gravity.

The invention consists broadly in a pivoted shoe suspended on the inside ofthe wheel, and with means for normally holding the same elevated beneath the vehicle body, the shoe .when dropped falling into the path of the wheel which rides into said shoe, and is lifted from the ground, the ground engaging'face of the shoe being suitably roughened.

The invention also includes means for suspending the shoe so that when release its fall will be cushioned.

With these objects in view the invention also consists in the novel features of construction hereinafter described, pointed out in the claims, and shown in the accompanying drawings, in which:

Figure 1 is a sectional side view, the inner side of a wheel being shown and a vehicle body being dotted. Fig. -2 is a View looking from the front toward the wheel, parts being tion. Fig. 3 is asection on the line 3-3 of Fig. 1. Fig.4 is a section on the line 4-4 of Fig. 1.

In the drawings 1 represents afoot operated ver which rocks a suitable link 2, which in turn swings a hook lever 3, these parts being pivotally' connected by a rod4.

The hook 3 engages a which in turn is pivotally connected to a shoe 7. This shoe is preferably in pivotally hung on bearing plate or bracket otherwise mounted on the rear axle,- the exact manner of fasteningthe bracket or its exact form not being regarded as material.

The plate forming the shoe 7 is laterally angled as at 7 to receive the wheel tire when dropped into the path of the wheel, whereby displacement of the tire is prevented by use of the shoe.

A second piston rod 10 is pivotally connected to a bracket 13 carried by the underside of the vehicle frame or body 14. The rods 6 and 10 have heads 16 and 17 which work in a-cylinder 11, said cylinder being provided with longitudinally arranged air vents 12. A spring 15 serves to return the parts to normal position.

The parts are normally suspended as in Fig. 1. To operate the foot lever 1 is pushed forwardly thereby rocking the link 2 and through the rod 4 derside to prevent skidding.
